l. A. BAUM `METAL AND WOOD FRAME mad Jan. 20I v192s Patented July 7,1931 UNITED STATES PATENT OFFICE METAL AND Woon FRAME Application filedJanuary 2o, 192s. serial No. 248,157.

My invention relates to buildings and par-v ticularly to novel framingfor wall openings therein. f

An object of my invention is to provide a 6 composite frame structurecomposed of metal Y and wood and so arranged that the utmost rigidity isassured. This result is secured by utilizing a channel shaped framestructure corresponding to a rough buck, the metal structure serving asa support for one or more Wood blocks rigidly secured to the support,the wood blocks serving as a mounting for the usual jamb or otherframing for the openlng.

The advantage of the illustrated construction is that the wall andopening may be completed with the assurance that there will be no cracksin the plaster at the junction of the frame with the wall such ascommonly occur due to shrinkage or warping of a wood buck, yetpermitting the use of wood trimy without requiringy special fasteningmeans therefor.

In ordinarypractice the wood rough bucks cannot be erected with accuracyand even though they are so erected, the tendency to shrinkage andbuckling is apparent in a short time. It is, therefore, necessary toaccurately assemble the finished wood frame or jamb before it is erectedand attached through wedging or blocking, this blocking taking up thevariation between the sides of the rough bucks and the finished frame.'t

With the steel frame or buck such as disclosed herein the situation isquite different.

The Vsteel frame members are made very ,accurately and so erectedWithout any skill on the part of the workman. The wood blocks WithinVthe steel frame are retained without any possibility of buckling ornon-alignment. Therefore, the finished frame can be erected as threeloose pieces nailed directly to the wood blocks which saves asubstantial amount of time in assembling' the pieces before in#v Theinvention will be more readily underi stood by referring to theaccompanying drawings, in which;

Fig. 1 is a sectional view through a Wall constructed in accordance withmy invention, the parts being shown in perspective;

- Fig. y2 is a sectional view on the line 2 2 of Fig. 3, and c g Fig. 3is a sectional View on the line'S-B of Fig. 2. f

Fig. 4 is a perspective view of the frame member of my invention. f Inthe drawings I have illustrated a metallic frame member comprising a web10 and side fianges 11., -Ears 12 arey struck out at intervals from theweb ofthe channel and bent backwardly substantially in line with theflanges 11. These ears serve as means for positioning the channelrelative t0 the tile y or other wall elements 13. As a means for`anchoring the channel relative to the tile,` I kmay provide the loopedmember 14 having hook ends 15 that project-into theV openings formedy bystriking out the ears and lie back of the web 10 of the channel.

The vertical and horizontal members of the metal frame may be joined attheir ends in any suitable manner, preferablyin'the manner illustratedin my co-.pending appli cation, Serial 248,156 filed of even dateherewith.V f

At intervals in the length' of the channel frame members, I -mount Woodblocks 16 best shown in Figs. 2.and 3 same being held in placeby meansofnails 17 projectingv through the flanges 11 of the channel.l Tothe woodblocks I secureV a wood element 18 in the nature of a sub-buck, theWidth of the board 18 ybeing vsubstantially exactly that of thethickness ofthe finished wall including the plaster 19. The sub-bucktherefore serves as a plaster ground.- A jamb 20 is4 positioned by meansof the usual wedges 21, and molding 22 of any suitable shape is appliedto the face of the wood members 18, 95

20 and overlie the joint with the plaster.

A construction such as described may be easily and cheaply applied withthe assurance of full rigidity and permanency of the. frame relative tothe plaster and yet vpermitting unlimited selection of the decorativewood trim.

The forni and arrangement of the parts may be varied within limitswithout departure from the spirit of my invention.

I claim:

l. In framing Yfor wall openings the combination of a metal channel, theflanges of which project into the opening, ears struck out of the webof' the channel and projecting rearwardly in line with said flanges andserving as means for positioning the chan` nel relative to a wall, awood block fixed in the channel, a sub-buck secured to the block andserving as a plaster ground, a casing element secured to the sub-buck,and molding overlying the edges of the casing element and the sub-buckand secured thereto.

Q. In framing for wall openings, the coinbination of a metal channel,the flanges of which project into the opening, ears struck out of' thewel) of the channel and projecting rearwardly in line with said flangesand serv ing as ,means for positioning the channel relative to a wall, aplurality of wood blocks fixed in the channel in vertically spaced.relation, a sub-buck secured to the block and serving as a plasterground, a casing element secured to the sub-buck, and molding overlyingthe edges of the casing element and the sub-buck and secured thereto.

3. In framing for wall openings, the comhination of a metal channel, theflanges of which project into the opening, ears struck out of the web ofthe channel and projecting rearwardly in line with said flanges andserving as means for positioning` the channel relative to a wall, a woodblock in the channel, fastening means projecting through the flanges ofthe channel into the block, a sub-buck secured to the block and of'suhstantially the exact width of the finished plaster wall whereby it isadapted to act as a plaster ground, and a jamb mounted on said subebuck.

4l. In framing for wall ojiienings the cembination of a metal channel,the flanges of which project into the opening, ears struck out of theweh of the channel and projecting rearwardly in line with said flangesand serving as means for positioning the channel relative to a wall.. awall anchor in the form of a loop having hook ends adapted to enter theopenings caused by striking out said ears, wood blocks fixed in saidchannel in vertically spaced relation, a sub-buck secured to the blocksand acting as a plaster ground, and a jainb secured to the sub-buck.

In testimony whereof I have affixed my signature.

ISAAC A. BAUM.
